Product Details
應用(yòng)信息
液體(tǐ)塗料
特性和優點
DISPERBYK-2152 具(jù)有(yǒu)高度枝化的化學(xué)結構,設計用(yòng)于無溶劑環氧以及其它反應型體(tǐ)系,如雙組份聚氨酯和酸催化體(tǐ)系。在顔填料的研磨過程中(zhōng),助劑的聚酯側鏈被壓縮,同時胺基團對顔料或填料表面的附着力增加。顔料親和基團得以吸附在顔填料表面,聚酯側鏈則依然包裹胺基團,避免其與環氧樹脂反應。該助劑可(kě)顯著降低粘度,不會與樹脂發生反應,從而獲得長(cháng)期貯存穩定性。DISPERBYK-2152 可(kě)良好的潤濕和解絮凝顔料。該助劑相容性寬,對塗料的性能(néng),如耐黃變、金屬附着力或防腐蝕性,沒有(yǒu)負面影響。
DISPERBYK-2152 符合德(dé)國(guó)建材産(chǎn)品健康評估委員會 (AgBB) 的環保要求。
推薦用(yòng)于
工(gōng)業塗料、木(mù)器和家具(jù)塗料、防腐塗料
推薦用(yòng)量
% 助劑用(yòng)量(購(gòu)入形式)基于顔料
無機顔料: 5-10 %
二氧化钛: 1-3 %
有(yǒu)機顔料: 20-45 %
炭黑: 20-80 %
上述數據為(wèi)經驗用(yòng)量,最佳用(yòng)量需通過一系列梯度試驗确定。
加入方法和加工(gōng)指導
為(wèi)獲得最佳效果,應在加入顔料前将助劑加入研磨料中(zhōng),這樣可(kě)以充分(fēn)發揮助劑的功效。先将研磨料的樹脂和溶劑組份預混合,然後在不斷攪拌下慢慢加入助劑。助劑充分(fēn)分(fēn)散後,再加入顔料。

加入方法和加工(gōng)指導
潤濕分(fēn)散劑應加入到研磨料中(zhōng),這是獲得最佳效果的唯一方法。應先将研磨料的樹脂和溶劑組份預混合,然後在不斷攪拌下慢慢加入該助劑。在助劑充分(fēn)分(fēn)散後,再加入顔料。
膠粘劑和密封膠
特性和優點
該助劑改善無機填料的潤濕分(fēn)散,如碳酸鈣、氫氧化鋁 (ATH),同時也适用(yòng)于鋁粉和氧化鋁填料。該助劑可(kě)降低粘度并提高填料添加量。
推薦用(yòng)于
該助劑尤其推薦用(yòng)于環氧和聚氨酯膠粘劑。
